Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The runtime behavior is consistent with a Vite diagnostics plugin: its default bridge host is loopback, and its client reports browser events to that bridge. The scanner’s bridge signal is explained by the manifest’s matching LensMCP bridge dependency and the source’s local event transport. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-14T09:32:18.470Z - **Finished:** 2026-10-14T09:33:23.568Z - **Download time:** 520 ms - **Static scan time:** 48 ms - **AI review time:** 64529 ms - **Total time:** 65098 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. When enabled in Vite development, the plugin instruments browser events and sends diagnostics to its bridge. - **Trigger:** A Vite host loads the plugin for development; it is enabled by default. - **Impact:** This supports local debugging; the inspected source does not establish an attack or external credential disclosure. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T09:33:23.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The injected client sends readiness, console, error, and fetch metadata over WebSocket to the bridge, which defaults to loopback. - **Rationale:** The runtime behavior is consistent with a Vite diagnostics plugin: its default bridge host is loopback, and its client reports browser events to that bridge. The scanner’s bridge signal is explained by the manifest’s matching LensMCP bridge dependency and the source’s local event transport. - **Files touched:** package.json, index.js, lib/plugin.js - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points package imports to index.js and lists matching LensMCP bridge and instrumentation dependencies., The plugin defaults to enabled for Vite serve and uses 127.0.0.1 as its default host., The development server creates a tokenized bridge on that host using an ephemeral port by default., The injected client sends browser readiness and diagnostic events, including console and fetch metadata, through the bridge., The entrypoint exports the Vite plugin and its bridge envelope helper. - **Evidence against:** The inspected source shows no package-selected external recipient or credential collection; the observed event transport is the plugin’s local development bridge. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.24.4. - Review the evidence and your use of @lensmcp/vite-plugin@1.24.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 2.
